Things I liked: I cannot believe that this is a breakbarrel rifle considering how insanely accurate it is. I own several high quality springers like the AA 200TX, RWS 54 King and this rifle is as accurate. I needed a less expensive rifle to take care of a rat problem that I had in my office and didn't want to carry a rifle back and forth. I ordered an RWS 34 because I saw the high rating and low price. Ordered a Hawke air max scope and it had so much barrel droop that it was impossible to zero in. Caked Greg at PA and took care of replacing it right away. Mounted the scope and could not group anything smaller than 5" inches! Greg asked me to return the scope. New scope mounted same thing. We concluded it couldn't be the scope and he recommended replacing it w/ the HW50S. From the moment I opened the box I knew there would be a difference. Mounted scope and at 25 yds, nothing but dime size holes. Seriously this rifle is everything that the 34 is not. Excellent quality! Simple German engineering

Things I would have changed: Wish it had a little more velocity. 100 FPS more, but haven't had problems nailing rats, so they may be onto something with this velocity.

What others should know: Something is up with RWS/Diana 34 because I can't imagine that the bad luck I had with two of their rifles is normal, but nothing would surprise me nowadays as quality is beginning to take a back seat over profits. All I can say is the the HW50S is like a Mercedes compared to the RWS.

Things I liked: Got my HW50 last year. JBS Exact pellets Less then 5/16 inch groups at 25 yards. With 4x12 scope. Put over a 1000 rounds down range. I was thinking will this rifle shoot better with a Full tune and not have so much spring bounce and noise. I got on goggle looking into tune up. So I got a hold of John in PA. This is what he did. Befor the Tune. 10 shot strings FPS Average was 749.3. After the Tune 10 shot string FPS Average 798.3. Trigger tune is crisp. This is a hole deferent rifle in the way it shot out of the box. I am getting cloverleaf groups at 25 yards bench rest shooting and it shoots a lot quieter. I think the word is Tack Driver!

Things I would have changed: After the tune nothing. Rodents beware there's a HW50 in town. LOL

What others should know: The only thing is that the tune did increase the Foot pounds of cooking Effort for the increase in FPS. I am 63 and no problem with cooking this rifle all day.

Things I liked: I was a little surprised at the accuracy of this rifle right out of the box. I expected to need a few hundred shots to break it in and find a pellet that it liked. What happened was that I cleaned the barrel and tried several pelet's and it grouped well with them all at 10 yards in my basement. I will have to get it outdoors to stretch out the range and find out what this rifle will do.

Things I would have changed: There is not anything bad to be said about this rifle. I am vry happy with it.
